A voluptuous man or woman who's thirst for cum is never quenched. A cum hog will go to any length to get creamy thick man gravy all over their face and mouth.

"Dude check out that cum hog"
"Aww dude she's collecting jizz from homeless men and putting it into a milk jug"
"FUCK!!! that fuckin cum hog is chuggin on that gallon of baby batter"
"No fuckin way...the bitch is regurgitating it back into the jug"
"What a fuckin nasty, slimy flesh cave"
